Reviews
“For those like me who hate to floss!: Ok, I'm in my 70's and I brush my teeth regularly but rarely floss. When I go in for my annual cleaning, my hygienist always asks if I'm also regularly flossing. I sheepishly reply, "Every now and then". At my latest visit she suggested I try using a cordless water flosser. She said I can use it in the shower. So I researched all the variations out there and read the reviews. I decided on purchasing this one. WOW! I'm astonished how…”
“It’s the best water flosser: I have been using this water flosser for a few months now, and I couldn't be happier with it! It works perfectly and leaves my mouth feeling incredibly clean every single time. The water pressure is amazing, and it is very easy to use and refill. It has completely upgraded my daily dental care routine. If you are looking for a reliable, high-quality water flosser, I highly recommend this one. 10/10!Read moreRead less”
“Best flosser owned to date: The online flosser has lasted a long time without recharging (march 2026-present). The flosser has a larger water tank than any of the previous flossers I have owned. The adjustable 4 water pressures a enough to hand any pressures and works well with sensitive gums. The dollar value is lower than others I have purchased a works much better than previous owned. I have not experienced any issues or anything that could be improved to date. The…”
“Better than dentist recommended brand: I bought this as a gift for a relative whose water flosser broke. She bought one that her dentist recommended, which cost more than three times the price of this unit. I was a bit worried that it wouldn't work as well because it was cordless compared to the corded one it would be replacing. I was wrong. She was extremely happy with the performance and said it was actually stronger and better at flossing. She also couldn't stop…”
“Overall Happy With This Purchase: Overall, I’m happy with this water flosser. The battery holds a charge very well, and I really like that it’s rechargeable, making it convenient for travel and everyday use.My only complaints are that the pressure settings could use a middle option—the high setting feels a little too strong, while the low setting doesn’t feel quite strong enough. Also, the power/mode button is positioned where I naturally hold the unit, so I occasionally hit…”
“Great Water Flosser: This water flosser is so easy to use and the best is it is easy to clean! It holds a charge for a couple of weeks and really works great! This is my first water flosser and I am so glad it is so easy to use. It can be messy and splash everywhere but if you close your mouth around it or use in the shower, then all is good! I also like that you can customize the pressure to start lower as you get used to it and increase as you get accustomed to it. I'm…”
“Convenient flosser and bang for your buck: Bought this water flosser to replace my older one that I got 5 years ago. I like how compact this flosser is without giving up functionality. It takes up a lot less room on my sink than a waterpik and works great for my needs. It has 3 strengths for the water pressure and a pulse mode which I haven't used too much yet. It comes with 2 standard nozzles, a tongue cleaning nozzle, and an orthodontic nozzle. I hadn't used a tongue…”
“Great little device: I ordered this Onlyone Flosser after a competitors flosser abruptly quit after a short period. Though I was unsure of this purchase at first I read product reviews and decided to buy this one. I have not been disappointed as it performs wonderfully and simply does the job on my teeth without any added drama. A simply versatile device with four settings and easily charged and refilled. I would buy another one but I expect this one to last for a long…”
